Equilibrium Bird Species Diversity in Atlantic Islands [PDF]
Current Biology, 2017 Half a century ago, MacArthur and Wilson proposed that the number of species on islands tends toward a dynamic equilibrium diversity around which species richness fluctuates [1]. The current prevailing view in island biogeography accepts the fundamentals of MacArthur and Wilson's theory [2] but questions whether their prediction of equilibrium can be ...

Fecundity of the squid Loligo vulgaris, Lamarck, 1798 (Myopsida, Loliginidae) off northwest Africa
Scientia Marina, 2000 Egg dimensions were 2.0-2.2 x 1.5-1.6 mm. Potential fecundity (all oocyte stock) of mature female L. vulgaris was estimated as 28,500-74,200 oocytes, including 3,500-30,500 yolk oocytes, 1,300-8,000 of those were ripe eggs in the oviduct.

First data on ovary maturation and fecundity in the squid family Histioteuthidae
Scientia Marina, 2001 The potential fecundity of histioteuthid squid ranges from 3,000 to 275,000 oocytes. During maturation a significant oocyte resorption occurs in many species; therefore only advanced maturing females can be taken into account for fecundity estimation.
